Introduction to Physical Science: Energy and Fuels Energy is defined as the capacity or power to do work‚ such as the capacity to move an object (of a given mass) by the application of force. Energy can exist in a variety of forms‚ such as electrical‚ mechanical‚ chemical‚ thermal‚ or nuclear‚ and can be transformed from one form to another. It is measured by the amount of work done‚ usually in joules or watts. All known forms of energy can be converted from one form to another. The Law of Conservation

harmful gases that vehicles are giving off. Forget ethanol or biodiesel. The next big thing in automotive fuel may very well be hydrogen. Automakers rapidly are closing in on making hydrogen fuel cell vehicles an everyday fact of life‚ with several test models set to debut over the next few years. Hydrogen fuel cells to power vehicles are desirable‚ experts say‚ because hydrogen is a renewable fuel that can be used to create electricity to run cars. A chemical reaction between oxygen and hydrogen produces

Fossil fuels are being used up at a faster rate than they can regenerate. The British Petroleum report provides alarming figures. At the current rate of consumption‚ the coal reserves on Earth will be spent within 110 years. Global reserves of oil and natural gas are even lower‚ and will be spent within the next fifty years respectively. Despite these statistics suggest that fossil fuels are a reliable long-term energy source‚ these numbers are misleading. Due to global population and energy

However‚ there is renewable sources of energy in wind and solar energy. In Deborah Snow article in the Newcastle Herald titled “Reliance on fossil fuels challenged” she talks about Cameron Clyne position on Australia climate change policy. Cameron Clyne is the former head of the National Australia Bank‚ therefore knows of the economic importance of continuous growth for a global economy. Clyne accepts

refers to any form of energy that is not derived from fossil fuels. Alternative energy sources like wind farms‚ solar cells‚ hydroelectric dams‚ biomass fuels‚ and nuclear power have been considered to be attainable sources that will be able to sustain the global population’s high demands. Traditional energy sources like oil‚ gas and coal are what the modern world knows and is most comfortable with‚ as its established fountain of fuel. Weighing the benefits and drawbacks of one power source over

fossil fuels due to the lacking of oil‚ gas‚ etc. An alternative energy source is ethanol (C2H5OH). It is an alcohol fuel manufactured by fermentation and distillation of crops that are high with starch and sugar‚ such as grains‚ sugarcane (most commonly used)‚ corn‚ and fruit. Other names for ethanol are ethyl alcohol‚ drinking alcohol‚ and grain alcohol. It can also be made from trees‚ grasses‚ woods‚ and plant waste. It is a colourless‚ flammable liquid that is categorized under bio-fuel. Brazil

The debt over burning fossil fuels and the impact it has caused on climate change as been discussed over years without answer as to say if the gradual warming of the earth is a natural process or if human activity has added to the acceleration of climate change or is the key behind it. Evidence of this is the hockey stick debt as temperature rise rapidly once humans became developed. One thing we do know is that there are many natural events that possibly could accelerate global warming but also

Petroleum‚ otherwise known as petrol‚ results in pollution during every stage of production‚ this ranges from: mining and recovery to refining‚ transporting and more importantly using it as fuel. Drilling wells is responsible for direct pollution due to oil spills; consequently‚ drilling also leads to the injection of watery liquids into the wells which are later distributed as drilling mud that often cause their own toxic pollution. Furthermore‚ the transporting of such oil by tanker ships have

Select a fossil fuel. How is this fossil fuel used? What are the adverse effects on the environment? The fossil fuel I would like to use and is the most popular fossil fuel would be oil. Oil is used into things like gasoline‚ which is used for very much all of our transportation needs still now and those in the past
